Need a Sachs shock spring, interchangeability with other shocks

Bloody must be, thought it was stock but obviously not.

Deffo think the calculator is junk.
Or my measurements, I'm a metric boy now.

Just do the conversion... 25.4mm per inch

I dunno.... I measured my coils (with a cheesy plastic caliper) and got 11.15mm on my 310; which is a fair distance from your 12.7mm ...and that's including the powder coating.

Not saying the bikes are related (certainly not KYB vs Sachs), but how sure are you of that spring wire diameter on your 360?

Seems I recall a fairly easy way of determining spring rate using a lever and a scale, and measuring the distance the spring compressed while noting the force on the scale (steady-state, obviously). Then maybe dividing by the number of free coils?? I can't remember shit nowadays. [edit: probably no division, we're measuring the entire spring rate]

hell, I can't figure out why you couldn't do that (above) with the spring still on the shock (well, maybe a few setup issues, but still...)

good luck.

Chad- betcha juicy is pretty good at unit conversions. Most of the English hafta convert between stones, kilograms, pounds, imperial gallons, rods, meters, feet, pints, litres, hectacres daily and do it without thought. Kinda like Canadians being pretty comfortable with metric and traditional US measurements- but taken to the next level.

goddamn it.... I am really feeling old.

sorry Chad, you must still be on probation. I did not see your 1/2" wire observation until way after I posed the same question.

Will get the callipers out an re measure.
That was with the nearest metal ruler I had.

Regarding Converting yeah I do alot of crossover sockets but only common ones.14mm =9/16th 19=3/4etc
Not areas too much.
Thing that gets is we do miles an hour but measure milage in gallons not liters ...
